DUMPMAN RV Sewer Hose Kit 20 ft — One‑Piece TPE/Vinyl, Clear 90° Adapter & Leak‑Resistant Bayonet Fittings

The DUMPMAN 20 ft RV Sewer Hose Kit is a one‑piece, heavy‑duty wastewater hose designed for secure, flexible and visible dump connections at campsites.

Keep campsite sanitation simple with a single, stretchable sewer hose that won’t kink or separate. Built from resilient TPE and reinforced 24‑mil vinyl, this 20‑foot line is made to resist abrasions, UV exposure and the occasional footstep. The kit includes a clear 90° adapter for visual confirmation of flow and patented 4‑prong bayonet fittings with an integrated rubber seal to reduce leaks and make hookup easy.

How does this hose handle campsite wear and tear?

The DUMPMAN sewer hose was engineered for repeated use in outdoor conditions. TPE and thicker vinyl give it flexibility without sacrificing puncture resistance, and the material rebounds if compressed. That combination lowers the chance of cracks, rips or UV degradation during extended trips.

• 20 ft one‑piece design avoids weak joint connections.
• TPE core with 24‑mil vinyl outer layer for abrasion and UV resistance.
• Flexible enough to spring back after being stepped on or rolled over.

Will it connect to different dump station outlets?

The included clear 90° adapter accepts multiple common dump pipe sizes so you can hook up quickly at most parks. The adapter fits 3" slip, 3", 3‑1/2" and 4" NPT threaded pipes, giving compatibility across standard municipal and private dump stations. Seeing the flow through the adapter also helps you know when emptying is complete.

• Clear elbow adapter shows wastewater until the tank is fully drained.
• Fits 3" slip, 3", 3‑1/2" and 4" NPT pipe sizes for wide compatibility.
• 90° angle reduces hose strain and keeps the connection compact.

How does the kit prevent leaks during use?

DUMPMAN’s bayonet style fittings lock the hose to an RV outlet with four prongs for a snug mechanical hold. A molded rubber seal sits inside the fitting to stop drips at the connection point, and the one‑piece hose eliminates joint failures common with multi‑piece assemblies. The combination yields a reliable, low‑maintenance connection at dump time.

• Patented 4‑prong bayonet fittings for secure, twist‑lock attachment.
• Built‑in high‑quality rubber gasket for a tight seal and reduced leaks.
• One‑piece construction avoids weak seams and quick disconnects.

How easy is the hose to store and move around the campsite?

The flexible TPE construction coils easily for compact storage and rebounds after being coiled or stepped on. At 20 feet it offers extended reach to place the RV where you want without needing extra connectors. Rugged materials mean you can carry and handle the hose without constant concern for punctures.

• Flexible enough to coil for storage in RV compartments or tote bags.
• Extended 20 ft length eliminates the need for additional extension pieces.
• Durable construction withstands repeated handling and outdoor conditions.
